Abstract: FIELD: pharmacy. 
     SUBSTANCE: invention proposes medicinal formulations of stavudine with sustained-release effect comprising granules prepared by extrusion-spheronization and covered by isolating coating. Granules involve coating for sustained releasing also. Granules are prepared by mixing stavudine, spheronizing agent, suitable solvent, magnesium stearate taken in stabilizing amount in the presence of water taken in limited amount that is necessary for carrying out extrusion-spheronization process. Invention involves also solid gelatin capsules containing similar granules containing other therapeutic agents in addition to stavudine granules that are useful for retroviral infections. It has been shown that magnesium stearate, in contrast to other similar pharmaceutical additions, stabilizes stavudine against decomposition in hydrolysis and protects granules from color change from yellow to brown. Stavudine granules with magnesium stearate don't cause reducing activity of stavudine in hydrolysis that is associated with a method for their preparing. 
     EFFECT: improved preparing method, valuable pharmaceutical properties of granules.

The latter is gradually cooled to 20-26 о С, after which is added seed of one of enantiomers, solution is stirred for 30-60 min, filtered non-racemic propranolol hydrofluoride enantiomer having the same configuration as the seed previously added. Racemic compound is added to mother liquor in amount compensating separated precipitate, mother liquor is heated at 55-70 о С to entirely dissolve added material and seed of the other enantiomer is added. Subsequent crystallization gives precipitate rich in the other enantiomer and process is several times repeated. Enantiomer purity is then raised by recrystallization. Non-racemic propranolol salts are finally converted into free propranolol enantiomers. Method of invention can be used in pharmaceutical practice.

Abstract: FIELD: machine engineering, namely tool strengthening method, possibly for increasing operation resource of metal cutting tools, for example of cold forging punches. 
     SUBSTANCE: method comprises steps of saturating working surface of tool with nitrogen by depth 30 - 40 micrometers before applying multiple-layer coating for performing compensation of difference of thermal-physical-mechanical properties of coating and tool materials; applying onto nitrogen-saturated surface mutually alternating intermediate and compensating layers. Hardness of next intermediate layer is higher than that of previous one. Intermediate layers provide  gradual change of hardness from substrate to surface of coating and therefore they provide increased impact viscosity. Compensating layers made of pure titanium or chrome provide bonding between layers. After applying each layer, ion polishing is realized. Last surface layer is made of plastic material used for running and concealing micro-cracks of wear-resistant layer of coating.
